belted kingfisher
The belted kingfisher (''Megaceryle alcyon'') is a large, conspicuous water kingfisher, the only member of that group commonly found in the northern United States and Canada. It is depicted on the 1986 series Canadian $5 note. All kingfishers were formerly placed in one family, Alcedinidae, but recent research suggests that this should be divided into three. All six New World kingfishers, together with three Old World species, make up the new family Cerylidae.

Both sexes have a slate blue head, large white collar, a large blue band on the breast, and white underparts. The back and wings are slate blue with black feather tips with little white dots. The female features a rufous band across the upper belly that extends down the flanks. Juveniles of this species are similar to adults, but both sexes feature the rufous band on the upper belly. Juvenile males will have a rufous band that is somewhat mottled while the band on females will be much thinner than that on adult females.
